What’s this worm?

Hi,

I just received an order of corals from an online vendor. I dipped my corals in CoralRX and Reef Dip sequentially according to their instructions.

after putting the corals in my DT, I noticed some fan-like worms on the base of a colony of Zoas. Below is a picture showing what I got.

what are these? Anything I should worry about?

Thank you! I was starting to freak out!
